This invention relates to marking, printing and embossing machines, and has for lts general object and purpose to yprovide such a machine for printing or embossing plain l or 'lustrous letters, designs, emblems or other identifying indicia upon articles composed in whole, or in part, ofnleather, liber paper, textile'fabrics or other analogous materials.

vAs the"various articles upon which the machine is designed tooperate may more or 'S20 irrespective of such thickness variations,

whereby possible injury or damage to the article is avoided, and the letters or other printed impressions are in all cases clearly visible and legible. L 1. Y f

. It is also an object of my present invention to provide a device for, accomplishing the above result which consists ofvery few simply constructed parts capable of ready application to such marking or embossing machines '30 now. in general useA and without materially increasing: the manufacturing cost thereof.

With the above and other objects. in view,

the invention consists in the improved marking-printing or embossing machine, and the -'35 combination and arrangement of the several elements constituting the essential features of my present invention, as `will be hereinafter more fully described, illustrated in the accompanying drawing and subsequently incorporii ated in the subjoined claims.y

VIn the drawingwhereinl have illustrated one simple andfpractical embodiment of the device and inwhichsimilar referencecharacters designate corresponding-parts through- VICTOR .WEINGARTNEMOF STQALBANS, NEW YORK, AssIGNoR moronnars, cUsHMAN Y Figure l is a side elevation of one type of marking or embossing machinehaving a preferred form of my invention applied thereto; Fig. 2 is av plan view as indicated by the line 2--2 of Fig. 1; Y

Fig. 3 is an enlarged sectional view taken on the line 3-3 of Fig. 2; and Fig. 4 isfa fragmentary detail section of certain of the parts shown in Fig. 3. i

' For thepurpose ofjillustration, I have shown my present invention as applied to a markingor embossing machine ofi-that general character upon which numerous patents have hereto been issued to MaX A. G. Luedtke and Hugo Hoffmann. yMoreparticularly, in the drawing I have illustrated substantially the same machine as is shown inthe pending application of these inventors, Serial No. 375,613, liled July 3, 1929, V and in which a single typecarrying disc or wheel is'rotatably supported in a casing or housing, said housing bein pivotally4 mounted on' a base so that toget er with the wheely it may be vertically moved or oscillated towards and from an article supporting platen orcarriage. With' this movable vtype wheel or disc, there is associated means for automatically feeding a tape or kstrip coated with metallic foil between the wheel and the platen so astopresent a new portionof the tape for each impression. For the purpose ofthe present explanation, al general reference to this machine of the above application will suliice. Thus, upon reference to the drawing, it will be seen that the yhousing lor casing 5 for the rotatably adjusted wheel or disc 6 is suitably vmounted atk its lower end upon a horizontal axis supportedv on the base 7,'said1wheel upon its periphery being provided. with the circumferentiallyspaced type elements showin at 8. ,Inf the present instance, each of these type elements issecuredto or integrally formed with teeth Aor projections 9 on the periphery ofthe disc.`

While my present invention,as.iwillrbe tal sliding movement in a plane parallel withV the axis of oscillation of the housing 5 and wheel 6. Mechanism is provided similar to that shown in the referred to pending application for imparting a step by step movement to this carriage or platen in th-e suc-v cessive printing of the letters. It will, however, be clear that any other suitable means for this purpose might be utilized.

The carriage 10 is provided along its forward edge with an upstanding longitudinal rib or ledge indicated at 12, and which provides the supporting surface for that part of the article which receives the impressions from the type elements 8. Any suitable means might be attached to this sliding carriage to project forwardly therefrom for the purpose of supporting and positioning the article as a whole and holding the same against shifting movement relative to the carriage.. Since this, however, constitutes no essential part of the present invention, it isnot herein shown or described in detail.

Upon the carriage 10, a gauge device is mounted for the purpose of limiting the depth of the impressions made by the type members 8 in the surface ofl the article. In the present instance, I have shown this gauge device as consisting essentially of a metal plate 13 of general rectangular form and provided at the opposite ends thereof adjacent its rear longitudinal edge with the ears 14, whichare pivotally attached as at 15 to opposite ends of the sliding carriage or platen. The other or forward edge of this gauge plateispreferably bevelled downwardly from its upper surface as indicated at 16, and adjacent to said bevelled edge of the plate'the same is provided with the longitudinally extending slot 17. Rearwardly of this slot, spaced downwardly projecting pins or studs 18 are fixed at their upper ends to saidfplatefand constitute stop means with which the article indicatedat A inserted beneath the gauge plate contacts, as clearly shown in Fig. 3 ofthe drawing. Rearwardly of the pivots lfor the gauge plate, a plurality of. longitudinally spaced coil springs 19 are interposed between the gauge plate and the carriage or platen 10, so thatsaid springs by their expansive actiontend to rock the gauge plate upon the carriage and yieldinglyhold its bevelled edge 16 in contact with the ribor ledge 12, as shown n Fig. 1 ofthe drawing.

The gauge plate 13 at one end thereof is formed with a laterally and rearwardlyY projecting finger-piece 2O which is inclined upwardly at a slight angle with respect to the plane of the plate 13 and provides a convenient means whereby said plate may be rocked or oscillated upon its pivots 15 against the action of the springs 19, so as to lift or elevate its forward edge 16 sufiiciently to permit of the insertion of the article A between said plate and the rib or ledge 12 on thecarriage.

.When the machine is used forprinting or marking plain ink impressions on the material, any suitable form of inking device may be provided within the housing 5V for inking the faces ofthe type elements 8- asthe disc 6 is rotated. Vhen lustrous letters or other impressions are to'be made, a metallic foil carrying strip is suitably mounted for movement between the letter wheel and the article supporting carriage or platen.. rIhis strip or tape which I have illustrated at 21 is also fed by astep by step movement in the oscillations of theletter wheel as the successive impressions are made. While various mechanisms might be devised foreffecting this movement of the tape, I; preferablyuse such ainechanisin as is shown in the pending application above referred to, and which has been found highly eiiicient and serviceable in machines of this type.

Having above described the several mechanical parts of my present improvement, upon reference to Fig. 3 of the drawing, it will be noted that when the gauge plate 13 is in superimposed relation to the article A extending rearwardly from the ledge 12 of the carriage, the forward bevelled-edge 16 of said plate ,projects slightly beyond the vertical plane of the rear edge of saidledge or rib12. When the wheel 6 is ymoved forwardly and` downwardly to printing position, withv the tape 21 interposed between a type element 8 and the surface of the article, said type element engages, the article immediately in advance ofthe forward edge of the plate 16 and the. corner orl shoulder of the lug 9, from which said type; element .projects by contact with the bevelled surface 16 of the plate, limits the depth of the impression made by the type element inthe surface ofthe article. It will also be noted that an adjacent type element 8 on the disc enters the slotV 17. in the gauge plate; Contacting engagement of saidlug upon said'bevelled surface is immediatelynoticeable, both audibly .and by reason of the additional. resistanceto any further downward movement of the type wheel. vWhen an article of greater thickness is to be operated upon, the forward edge ofthe gauge plate is elevated by depressing the finger extension 20 so that the edge 16v of said plate will be disposed for a greater distance above the surface of the ribv or ledge 12. Thus, this bevelled edge of the platewill 'in' the same manner limit the downward movement of the type Wheel, so that the depth of the impression which is made in the surface of said article Will be the same as in the case of the article of less thickness. Therefore, it Will be evident that by means of my lpresent im# provements, absolute uniformity in the depth of the impression is obtained regardless of the thickness of the material or article which is operated upon, so that in the case of the thicker articles, the impressions Will not be of such considerable depth as to impair the v easy legibility of the printed impressions, or

to possibly result in damage or injury to the material.

From the foregoing description considered in connection With the accompanying drawing, it Will be seen that I have provided a very desirable improvement in such marking or embossing machines, and one Which by reason of its simplicity, may be readily adapted or applied to such machines as are now in general use in the art. Also, it Will be evident that the gauge device as herein disclosed may be very easily and quickly operated and the article properly positioned With relation thereto so that it Will function in a reliabley and efficient manner to accomplish its intended purpose. I have herein shown and described a preferred mechanical form of my present improvements Which I have found fromactual use is best designed to achieve my intended purpose. It is, nevertheless, to be understood that insofar as the essential characteristics of my present inventionl is concerned, the same may also be exemplified in various other alternative structural forms, and I accordingly reserve the privilege of resorting to all such legitimate changes therein as may be fairly embodied Within the spirit and scope of the invention as claimed. j
